| 摘 要： | 提出了两种合成草甘膦中间体氨基甲基膦酸的方法:一种是以冰醋酸为溶剂、三氯化磷为膦酰化试剂;另一种是以水为溶剂、亚磷酸为膦酰化试剂.前者优于文献报道方法,后者未见文献报道,且流程短、污染小、成本低、具有应用前景.两种方法的产物收率均可达92%.

| Abstract: | There are two synthetic methods of aminomethylphosphonic acid which is a kind of metabolized substances of glyphosate.The first choosing CH 3COOH to be solvent and PCl 3 to be phosphonated regent,it is superior to those methods in literatures;the second choosing H 2O to be solvent and H 3PO 3 to be phosphonated regent,it was not reported before,and it is valuable to apply in industry because of shorter reaction process,less pollution and lower cost.The yield is 92% in every one method. |
